Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats uniformly around the outer circumference and shoulder of the tire, the opposite side perspective view being identical thereto;

FIG. 2 is a frontal elevational view thereof; and,

FIG. 3 is a side elevational view of the right side thereof.

In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread having a depth as best illustrated along the top and bottom edges of FIG. 2. In the drawings, the broken lines defining the sidewall, inner bead and the peripheral boundary between the claimed tire tread and the unclaimed sidewall depict environmental subject matter that forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
